The rate of change of a graph, is the slope of the graph.
The rate of change of the graph is 4.5
The points on the graph are:
[tex]\mathbf{(x,y) = (2,9) (4,18)}[/tex]
So, the slope (m) is calculated as:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m = \frac{18 - 9}{4-2}}[/tex]
[tex]\mathbf{m = \frac{9}{2}}[/tex]
[tex]\mathbf{m = 4.5}[/tex]
Hence, the rate of change of the graph is 4.5

Answer:
13 hours
Step-by-step explanation:
Charlie drove 495 miles in
= 9 hours
∴ Rate
= miles/hours
= 495/9
= 55 miles per hour
∴ No. of hours to travel 715 miles
= miles/miles per hour
= 715/55 hours
= 13 hours
Thus, 13 hours would it take to drive 715 miles.

Hey there!
39 = - u / 6
MULTIPLY 6 to BOTH SIDES
39(9) = (-u / 6)(6)
CANCEL out: the RIGHT side
KEEP: the LEFT side because it helps solve for the u-value
NEW EQUATION: -u = 234
DIVIDE -1 to BOTH SIDES
-1u / -1 = 234 / -1
CANCEL out: -1 / -1 because it gives you 1
KEEP: 234 / -1 because it gives you the result of the u-value
NEW EQUATION: u = 234 / -1
SIMPLIFY IT!
u = -234
Therefore, your answer is: [u = -234]
Good luck on your assignment and enjoy your day!

Can someone help me and explain this to me step by step?
Answers
Answer: 11/9
Step-by-step explanation:
First, convert two to 18/9. This is still equal to two but this makes it easier to answer the problem, because both of the terms have the same denominator. Now, since both of them have the same denominator, all you need to do is subtract the numerators, and put that over the denominator of 9. 18-7=11. So the answer is 11/9. This is an improper fraction, though you could also make it into a mixed number: 1 and 2/9.
Answer:
11/9
Step-by-step explanation:
Add a one under the 2. So that it becomes 2/1. Now you have the expression, 2/1 - 7/9. To subtract fractions, you need the denominators of the two fractions to be the same. We can put 9 as the common denominator. All you have to do in order for 2/1 to have 9 as its denominator, is to multiply 9 for both the numerator and denominator; 2/1 x 9/9 = 18/9. After that, your new expression would be 18/9 7/9. Just subtract across, 18 - 7 = 11, keep the denominator 9. The answer should be 11/9

Write blue, red, or orange in each section of the circle graph based on the following data:
There are 32 children. 25% of the children like blue, 16 children like red, and 8 children like orange.
Answers
25% of the children like blue, so 0.25*32 = 8 like blue. This is the same number of people who like orange.
So you'll have "blue" in one quarter slice and "orange" in another quarter slice.
So far, we've counted 8 blue + 8 orange = 16 total. Because there are 32 kids overall, this leaves 32-16 = 16 left. This matches up with the fact that 16 like red. This is half of 32, meaning we'll shade two quarter slices to indicate red. Put another way, you'll have "red" in two slices.
Check out the diagram below. That's one possible configuration (other combos are possible).
Ok so 25% like blue, so if we had to make an equation it would be 0.25 x 32 because that would give us the number of children who like blue. So, when we do that we get 8 which is the same amount of kids who like orange. So, 1/4 of that circle would be blue and another one fourth of the circle would be orange. So now we have to look at the red. It says "16 children like red" and we know that theres a total of 32 kids. So, since 1/2 of the circle was of the kids who like blue and orange, the other half has to show the amount of kids who just like red. Look at screenshot below to help.

Swimming Pool On a certain hot summer's day, 492 people used the public swimming pool. The daily prices are $1.50 for children and $2.50 for adults. The receipts for admission totaled $1060.00. How many children and how many adults swam at the public pool that day?
There were ______ children at the public pool.
Answers
Answer:
# of children = 170, # of Adults = 492 - 170 = 322
Step-by-step explanation:
Define C and A as
C = # of children
A = # of adults
Then,
A + C = 492
1.5C + 2.5A = 1060, so that
1.5C + 2.5(492 - C) = 1060
1.5C + 1230 - 2.5C = 1060
-C = 1060 - 1230
C = 170
